INDUSTRY INTELLIGENCE POWERED BY THE DCA society has a material cost. With more and more transactions, processes and communication transferring to the online world, energy usage and greenhouse gasses are increasing faster in this sector than most. A significant proportion of this is embodied energy in the hardware, which accounts for roughly 50% of overall impact. hardware required to generate it, there is also the energy needed to make the data centres in the first place, particularly the IT hardware. Another factor to consider is our increased use of digital, which is causing an explosion in the material cost. Upcoming projects While this is far from exclusive to the data centre sector – it is something we will need to be increasingly aware of going forward. The good news is that the industry is responding with new research projects into more sustainable solutions. There is good research on the horizon which should help with the problem. The Intereg-funded CEDaCI project, which Techbuyer joined in June 2019, is a three- year, multi-national project lead by London South Bank University. A shift in focus It has set some high targets, which include increasing reclamation and reuse of critical raw materials (CRM), extending product life through equipment reuse and remanufacture, reducing the use of virgin materials, waste and the environmental Historically we have focused on the energy draw of data centres and the introduction of wind and solar as a sustainable solution. Headlines report on issues like Google’s pledge to power 100% of its data centres with locally produced renewable energy as a ‘green story’. However, the use phase is only part of the story. Aside from the fact that renewable energy has its own material cost in terms of the the circular economy, which will begin in the near future and generate a white paper for the industry. Bringing together representatives from various companies in the sector, this will produce practical advice to the industry on how to improve material usage and system design. The options for achieving ‘greener’ data centres are numerous, and varied: but they’re still not the status quo, so not all IT companies will offer them up easily. impact arising from the growth in redundant equipment. At present, only 10% of CRM from the sector are recycled and recovered, but this will increase to 19% and 24% five and 10 years after the project ends; reuse of equipment will also increase to 65% and 75% respectively and at end-of-life overall product ‘waste’ will be reduced to 35% and 25%. It is an exciting project to be involved with because it will shine a light on a problem we have only been able to see parts of until now. Solid data on the amount of waste generated by data centres, exactly which materials it contains and where it ends up is difficult to find. The ProSUM project has an excellent resource in its urban mine platform for the EU, which tracks the flow of ICT from manufacture, use to disposal. The Data Centre Alliance has also invited us to chair a special interest group on www.intelligentdatacentres.com Steve Hone, CEO, DCA It is a shorter-term project than CEDaCI, but all the more valuable for that. Outlining what can be done in the short term is highly valuable. In among all this, there is the macro picture of the fantastic opportunity digital gives us for a more sustainable future. Green IT has the potential to be a saviour when it comes to limiting greenhouse gas emissions in other sectors. Visionaries describe a world where driverless cars are shared between multiple households, run by an algorithm that calculates who needs to be picked up when. Future sharing platforms like these are hailed as a part of the solution that the circular economy represents. As a sector, we can help maximise these benefits. Analysing the material cost of digital within the data centre, and taking steps to reduce this, will help create a brighter digital future for all. ◊ Issue 09 23
